So when I'm out and about I want it to be easy to toke up and I don't have to carry a stinking pipe or breaking my preroles. This is what I am using Snop dog G pen slim. Mini headchef grinder. Lighter is just for reference. I like it when I'm thinking I do fancy a smoke right now I can just pull the pen out and turn it on, quick drag turn off and pit it back easy? No its not as easy at I first thought. Yes the pen is great and gets me prity baked but it also has some bad bits. From left to right you have the battery, weed oven/element, mouth pice. Then a small 4 part grinder that can hold enough for one good size bowl or about 6/7 refills for the Vaporizer. The small oven meens it needs to be refilled after each drag. What I do is have a 5 second drag and then open it up and put a little more in and mix it up. I don't mind because it dosnt take long and I don't like getting high to quickly as I like the build up stage. I picked this up the day before and it didn't look like much and it was just picked from a bigger bag and put in my hand (only been in Austria for 2 weeks so still trying to find a good dealer. Dosnt look like much but packed a punch and it's is giving me a nice buzz.
